ABSTRACT

BACKGROUND: Clinical trials that have assessed the effect of revascularization in patients with stable coronary disease have routinely excluded those with advanced chronic kidney disease. METHODS: We randomly assigned 777 patients with advanced kidney disease and moderate or severe ischemia on stress testing to be treated with an initial invasive strategy consisting of coronary angiography and revascularization (if appropriate) added to medical therapy or an initial conservative strategy consisting of medical therapy alone and angiography reserved for those in whom medical therapy had failed. The primary outcome was a composite of death or nonfatal myocardial infarction. A key secondary outcome was a composite of death, nonfatal myocardial infarction, or hospitalization for unstable angina, heart failure, or resuscitated cardiac arrest. RESULTS: At a median follow-up of 2.2 years, a primary outcome event had occurred in 123 patients in the invasive-strategy group and in 129 patients in the conservative-strategy group (estimated 3-year event rate, 36.4% vs. 36.7%; adjusted hazard ratio, 1.01; 95% confidence interval [CI], 0.79 to 1.29; P = 0.95). Results for the key secondary outcome were similar (38.5% vs. 39.7%; hazard ratio, 1.01; 95% CI, 0.79 to 1.29). The invasive strategy was associated with a higher incidence of stroke than the conservative strategy (hazard ratio, 3.76; 95% CI, 1.52 to 9.32; P = 0.004) and with a higher incidence of death or initiation of dialysis (hazard ratio, 1.48; 95% CI, 1.04 to 2.11; P = 0.03). CONCLUSIONS: Among patients with stable coronary disease, advanced chronic kidney disease, and moderate or severe ischemia, we did not find evidence that an initial invasive strategy, as compared with an initial conservative strategy, reduced the risk of death or nonfatal myocardial infarction.

ABSTRACT

BACKGROUND: The COVID-19 pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to evolve as a global health crisis. Although highly effective vaccines have been developed, non-pharmaceutical interventions remain critical to controlling disease transmission. One such intervention-rapid, at-home antigen self-testing-can ease the burden associated with facility-based testing programs and improve testing access in high-risk communities. However, its impact on SARS-CoV-2 community transmission has yet to be definitively evaluated, and the socio-behavioral aspects of testing in underserved populations remain unknown. METHODS: As part of the Rapid Acceleration of Diagnostics-Underserved Populations (RADx-UP) program funded by the National Institutes of Health, we are implementing a public health intervention titled "Say Yes! COVID Test" (SYCT) involving at-home self-testing using a SARS-CoV-2 rapid antigen assay in North Carolina (Greenville, Pitt County) and Tennessee (Chattanooga City, Hamilton County). The intervention is supported by a multifaceted communication and community engagement strategy to ensure widespread awareness and uptake, particularly in marginalized communities. Participants receive test kits either through online orders or via local community distribution partners. To assess the impact of this intervention on SARS-CoV-2 transmission, we will conduct a non-randomized, ecological study using community-level outcomes. Specifically, we will evaluate trends in SARS-CoV-2 cases and hospitalizations, SARS-CoV-2 viral load in wastewater, and population mobility in each community before, during, and after the SYCT intervention. Individuals who choose to participate in SYCT will also have the option to enroll in an embedded prospective cohort substudy gathering participant-level data to evaluate behavioral determinants of at-home self-testing and socio-behavioral mechanisms of SARS-CoV-2 community transmission. DISCUSSION: This is the first large-scale, public health intervention implementing rapid, at-home SARS-CoV-2 self-testing in the United States. The program consists of a novel combination of an at-home testing program, a broad communications and community engagement strategy, an ecological study to assess impact, and a research substudy of the behavioral aspects of testing. The findings from the SYCT project will provide insights into innovative methods to mitigate viral transmission, advance the science of public health communications and community engagement, and evaluate emerging, novel assessments of community transmission of disease.

ABSTRACT

AIMS: ST-segment recovery (STR) is a strong mechanistic correlate of infarct size (IS) and outcome in ST-segment elevation myocardial infarction (STEMI). Characterizing measures of speed, amplitude, and completeness of STR may extend the use of this noninvasive biomarker. METHODS AND RESULTS: Core laboratory continuous 24-h 12-lead Holter ECG monitoring, IS by single-photon emission computed tomography (SPECT), and 30-day mortality of 2 clinical trials of primary percutaneous coronary intervention in STEMI were combined. Multiple ST measures (STR at last contrast injection (LC) measured from peak value; 30, 60, 90, 120, and 240min, residual deviation; time to steady ST recovery; and the 3-h area under the time trend curve [ST-AUC] from LC) were univariably correlated with IS and predictive of mortality. After multivariable adjustment for ST-parameters and GRACE risk factors, STR at 240min remained an additive predictor of mortality. Early STR, residual deviation, and ST-AUC remained associated with IS. CONCLUSIONS: Multiple parameters that quantify the speed, amplitude, and completeness of STR predict mortality and correlate with IS.

ABSTRACT

BACKGROUND: Non-clear cell renal cell carcinomas are histologically and genetically diverse kidney cancers with variable prognoses, and their optimum initial treatment is unknown. We aimed to compare the mTOR inhibitor everolimus and the VEGF receptor inhibitor sunitinib in patients with non-clear cell renal cell carcinoma. METHODS: We enrolled patients with metastatic papillary, chromophobe, or unclassified non-clear cell renal cell carcinoma with no history of previous systemic treatment. Patients were randomly assigned (1:1) to receive everolimus (10 mg/day) or sunitinib (50 mg/day; 6-week cycles of 4 weeks with treatment followed by 2 weeks without treatment) administered orally until disease progression or unacceptable toxicity. Randomisation was stratified by Memorial Sloan Kettering Cancer Center risk group and papillary histology. The primary endpoint was progression-free survival in the intention-to-treat population using the RECIST 1.1 criteria. Safety was assessed in all patients who were randomly assigned to treatment. This study is registered with ClinicalTrials.gov, number NCT01108445. FINDINGS: Between Sept 23, 2010, and Oct 28, 2013, 108 patients were randomly assigned to receive either sunitinib (n=51) or everolimus (n=57). As of December, 2014, 87 progression-free survival events had occurred with two remaining active patients, and the trial was closed for the primary analysis. Sunitinib significantly increased progression-free survival compared with everolimus (8·3 months [80% CI 5·8-11·4] vs 5·6 months [5·5-6·0]; hazard ratio 1·41 [80% CI 1·03-1·92]; p=0·16), although heterogeneity of the treatment effect was noted on the basis of histological subtypes and prognostic risk groups. No unexpected toxic effects were reported, and the most common grade 3-4 adverse events were hypertension (12 [24%] of 51 patients in the sunitinib group vs one [2%] of 57 patients in the everolimus group), infection (six [12%] vs four [7%]), diarrhoea (five [10%] vs one [2%]), pneumonitis (none vs five [9%]), stomatitis (none vs five [9%]), and hand-foot syndrome (four [8%] vs none). INTERPRETATION: In patients with metastatic non-clear cell renal cell carcinoma, sunitinib improved progression-free survival compared with everolimus. Future trials of novel agents should account for heterogeneity in disease outcomes based on genetic, histological, and prognostic factors. FUNDING: Novartis and Pfizer.

ABSTRACT

AIMS: Recently, a U-shaped association between PR-interval and the risk of developing atrial fibrillation was described, with higher risk in patients with long and short PR-intervals. Little is known regarding the association of PR-interval duration and mortality. The objective of the current study was to explore the relationship between PR-interval and major cardiovascular outcomes in patients with known coronary heart disease. METHODS AND RESULTS: Patients in sinus rhythm, undergoing coronary angiography at Duke University Medical Center between 1989 and 2010, who had significant stenosis in at least one native coronary artery, were included. Patients with arrhythmia, second- or third-degree AV-block, QRS > 120 ms were excluded. A total of 9,637 patients were included (median age 63, IQR 55-71 years, 67% men). After adjustment for relevant covariates, the risk of a CV event increased with a decreasing PR-interval (10 ms decrements) for PR-interval values <162 ms (all-cause mortality; HR 1.057, 95% CI 1.019-1.096, P = 0.0030, composite of death or stroke; HR 1.047, 95% CI 1.011-1.085, P = 0.0095 and composite of cardiovascular death or cardiovascular rehospitalization; HR 1.032, 95% CI 1.002-1.063, P = 0.0387). No statistically significant changes in the risk associated with PR-interval for values >162 ms were seen for any of the studied endpoints. CONCLUSION: In patients with coronary heart disease, a prolongation of the PR-interval was not independently associated with poor outcomes, but a PR-interval shorter than normal was associated with increased all-cause mortality and other major cardiovascular events.

ABSTRACT

PURPOSE: To define maximum tolerated dose (MTD), toxicities, and pharmacodynamics of capecitabine, oxaliplatin, bevacizumab, and everolimus in advanced solid tumor patients. DESIGN: This was a standard "3 + 3" dose-escalation trial. All subjects received bevacizumab 7.5 mg/kg on day 1 of each cycle. Doses for capecitabine, oxaliplatin and everolimus were modified per dose limiting toxicity (DLT). Baseline and on-treatment plasma biomarkers were analyzed. Archived tumor mRNA levels were evaluated for NRP1, NRP2 and VEGF-A isoforms. RESULTS: Twenty-nine patients were evaluable for toxicity and 30 for efficacy. Two DLTs were observed in cohort 1 and one DLT each was observed in cohort -1 and -1b. Grade ≥3 toxicities included neutropenia, hypertension, perforation/fistula/hemorrhage, hypertriglyceridemia, diarrhea, and thromboembolism. Twelve subjects experienced partial response (PR); 12 had stable disease as best response. Three of seven chemorefractory metastatic colorectal cancer (mCRC) subjects experienced PR; 8 of 15 chemonaive mCRC subjects experienced PR. Plasma TßRIII and IL-6 increased on treatment but without correlation to outcome. Increased VEGF165 levels significantly correlated with longer progression free survival. CONCLUSIONS: Everolimus with full dose capecitabine, oxaliplatin, and bevacizumab had unacceptable toxicity. MTD was: everolimus 5 mg daily; capecitabine 680 mg/m(2) BID days 1-14; oxaliplatin 100 mg/m(2) and bevacizumab 7.5 mg/kg, day 1. Activity was noted in mCRC.

ABSTRACT

AIMS: Atrial fibrillation (AF) and coronary artery disease (CAD) are common in older patients. We aimed to describe the use of antiarrhythmic drug (AAD) therapy and clinical outcomes in these patients. METHODS AND RESULTS: We analysed AAD therapy and outcomes in 1738 older patients (age ≥65) with AF and CAD in the Duke Databank for cardiovascular disease. The primary outcomes were mortality and rehospitalization at 1 and 5 years. Overall, 35% of patients received an AAD at baseline, 43% were female and 85% were white. Prior myocardial infarction (MI, 31%) and heart failure (41%) were common. Amiodarone was the most common AAD (21%), followed by pure Class III agents (sotalol 6.3%, dofetilide 2.2%). Persistence of AAD was low (35% at 1 year). After adjustment, baseline AAD use was not associated with 1-year mortality [adjusted hazard ratio (HR) 1.23, 95% confidence interval (CI) 0.94-1.60] or cardiovascular mortality (adjusted HR 1.27, 95% CI 0.90-1.80). However, AAD use was associated with increased all-cause rehospitalization (adjusted HR 1.20, 95% CI 1.03-1.39) and cardiovascular rehospitalization (adjusted HR 1.20, 95% CI 1.01-1.43) at 1 year. This association did not persist at 5 years; however, these patients were at very high risk of death (55% for those >75 and on AAD) and all-cause rehospitalization (87% for those >75 and on AAD) at 5 years. CONCLUSIONS: In older patients with AF and CAD, antiarrhythmic therapy was associated with increased rehospitalization at 1 year. Overall, these patients are at high risk of longer-term hospitalization and death. Safer, better-tolerated, and more effective therapies for symptom control in this high-risk population are warranted.

ABSTRACT

BACKGROUND: ISCHEMIA (International Study of Comparative Health Effectiveness With Medical and Invasive Approaches) did not find an overall reduction in cardiovascular events with an initial invasive versus conservative management strategy in chronic coronary disease; however, there were conservative strategy participants who underwent invasive coronary angiography early postrandomization (within 6 months). Identifying factors associated with angiography in conservative strategy participants will inform clinical decision-making in patients with chronic coronary disease. METHODS: Factors independently associated with angiography performed within 6 months of randomization were identified using Fine and Gray proportional subdistribution hazard models, including demographics, region of randomization, medical history, risk factor control, symptoms, ischemia severity, coronary anatomy based on protocol-mandated coronary computed tomography angiography, and medication use. RESULTS: Among 2591 conservative strategy participants, angiography within 6 months of randomization occurred in 8.7% (4.7% for a suspected primary end point event, 1.6% for persistent symptoms, and 2.6% due to protocol nonadherence) and was associated with the following baseline characteristics: enrollment in Europe versus Asia (hazard ratio [HR], 1.81 [95% CI, 1.14-2.86]), daily and weekly versus no angina (HR, 5.97 [95% CI, 2.78-12.86] and 2.63 [95% CI, 1.51-4.58], respectively), poor to fair versus good to excellent health status (HR, 2.02 [95% CI, 1.23-3.32]) assessed with Seattle Angina Questionnaire, and new/more frequent angina prerandomization (HR, 1.80 [95% CI, 1.34-2.40]). Baseline low-density lipoprotein cholesterol <70 mg/dL was associated with a lower risk of angiography (HR, 0.65 [95% CI, 0.46-0.91) but not baseline ischemia severity nor the presence of multivessel or proximal left anterior descending artery stenosis >70% on coronary computed tomography angiography. CONCLUSIONS: Among ISCHEMIA participants randomized to the conservative strategy, angiography within 6 months of randomization was performed in <10% of patients. It was associated with frequent or increasing baseline angina and poor quality of life but not with objective markers of disease severity. Well-controlled baseline low-density lipoprotein cholesterol was associated with a reduced likelihood of angiography. These findings point to the importance of a comprehensive assessment of symptoms and a review of guideline-directed medical therapy goals when deciding the initial treatment strategy for chronic coronary disease.

ABSTRACT

BACKGROUND: The benefit of oral anticoagulation therapy with warfarin for stroke prevention in atrial fibrillation (AF) is directly dependent on the quality of anticoagulation (QoA), which in the US is provided predominantly in the community setting. With the emergence of new oral anticoagulation agents, the current QoA needs to be assessed. OBJECTIVES: The purpose of our study is to define the QoA with warfarin in patients with nonvalvular AF who are managed exclusively in community practices, and to compare the quality in the community setting with the quality demonstrated in the recent large randomized control trials. In addition, this study will assess the differences in the QoA based on cardiology vs primary care practices. METHODS: This is a retrospective, observational, multi-center study of 392 patients with AF in the community who were initiated on anticoagulation with warfarin for stroke prevention. International Normalized Ratio (INR) values were collected over a one-year period and the QoA was expressed as time in therapeutic range (TTR) calculated by the linear interpolation method. RESULTS: One hundred patients from cardiology practices and 292 patients from primary care were studied. During the one-year period, the overall mean TTR was 56.7%. The TTR in the primary care vs cardiology practices was 55.3% vs. 60.8% (p=0.02). Both practices had similar percent of time below therapeutic range, 29.8% vs. 29.2%. However, the primary care practice patients were above the therapeutic range 15% of the time vs. 10% in cardiology (p<0.001). There were one death secondary to intracranial bleed and one major bleed in the primary care group. There were no strokes during the study period in either group. CONCLUSION: The QoA with warfarin, as assessed by TTR, in the current community setting remains suboptimal, and there has been little to no improvement in current clinical practices. TTR should be considered when assessing the recent comparative studies evaluating novel pharmacologic agents to warfarin for the treatment of AF. SUBJECT AREAS: Arrhythmias, preventive cardiology, anticoagulation, thromboembolism, cardiovascular disease risk factors.

ABSTRACT

Objective: To describe the results of the Sertraline Pediatric Registry for The Evaluation of Safety (SPRITES) outcome measures of cognitive, emotional, and physical development following long-term treatment with sertraline (for up to 3 years) in children and adolescents aged 6-16 years. Methods: SPRITES was a long-term, multicenter, open-label, prospective observational study designed to compare physical and psychological development in pediatric patients exposed to sertraline (with or without psychotherapy) or psychotherapy alone in usual care settings. Data were summarized descriptively, and outcomes were evaluated using a marginal structural model. Results: Between April 2012 and September 2020, 941 patients across 44 U.S. sites participated in the study. At baseline, 695 participants were exposed to sertraline (physician prescribed) with or without psychotherapy, and 245 participants were exposed to psychotherapy alone. Of these, 432 participants (46.0%) completed the full 3-year study follow-up. No significant changes across time were found in standardized height, BRIEF (Behavior Rating Inventory of Executive Function), Trails B, and Tanner stage based on cumulative sertraline exposure or exposure since the last visit. Change in mean standardized weight across time was positively associated with both cumulative sertraline exposure (p = 0.02) and exposure since the last visit (p = 0.029). The mean changes from baseline across time in standardized weight were standard deviations of 0.02, 0.03, 0.16, and 0.17 at months 3, 6, 30, and 36, respectively. However, this finding was not observed in the mean change across time in standardized body mass index, which was not statistically significant. Conclusions: Results are consistent with normal development. Although a statistically significant finding for standardized weight was observed in comparative analyses, the magnitude of the change is small and observed at higher doses of sertraline only. No other significant differences were observed between the "sertraline" group and the "no pharmacological therapy" group on other primary outcome measures.

ABSTRACT

BACKGROUND: In several studies, prolongation of the corrected QT (QTc) interval has been associated with an increased risk of cardiac events. However, data on race and gender variation in the QTc and its associated risk of death are lacking. METHODS: We prospectively followed 19,252 subjects who underwent cardiac catheterization and had at least 1 native coronary artery stenosis ≥75%. Automated QTc measurements were obtained from a baseline electrocardiogram. RESULTS: The mean age of the population was 62.4 years, with 35% being female and 20% being black. The QTc varied by gender and race (417.9 ± 34.4 ms in men and 433.4 ± 33.6 ms in women, 422.1 ± 34.3 ms in whites and 428.1 ± 36.9 ms in blacks; P < .0001 for both). Risk factors most strongly associated with a prolonged QTc were lower ejection fraction, higher diastolic blood pressure, history of myocardial infarction, and lower glomerular filtration rate. Black race and female gender were also independently associated with a prolonged QTc, after adjustment for cardiac risk factors. Moreover, there was an independent association between QTc and all-cause mortality (hazard ratio 1.037 per 10-ms increase, P < .0001). The increased mortality risk associated with a 10-ms increase in the QTc interval was significantly greater for men compared with women (4.6% vs 2.4%, P = .004) and slightly greater for blacks compared with other races (5.0% vs 3.3%, P = .057). CONCLUSIONS: Among patients with coronary artery disease, QTc prolongation is independently associated with all-cause mortality. The increased mortality risk is higher for men than for women, with a trend toward higher mortality in blacks.

ABSTRACT

BACKGROUND: Older patients with atrial fibrillation (AF) and coronary artery disease (CAD) face high risk of stroke and bleeding with antithrombotic therapy. Balancing safe and effective use of aspirin, clopidogrel, and warfarin in this population is important. METHODS: From the Duke Databank for Cardiovascular Disease, we identified patients with AF ≥65 years old with angiographically confirmed CAD from 2000 to 2010. Antithrombotic use was described across age and Congestive heart failure, Hypertension, Age >75 years, Diabetes, prior Stroke/transient ischemic attack (CHADS(2)) stroke risk and Anticoagulation and Risk Factors in Atrial Fibrillation (ATRIA) bleeding scores. Death and the composite of death, myocardial infarction, and stroke by antithrombotic strategy were reported. RESULTS: Of 2,122 patients ≥65 years old with AF and CAD, 477 (22.5%) were ≥80 years old; 1,133 (53.4%) had acute coronary syndromes. Overall rates of aspirin, clopidogrel, and warfarin use were 83.4%, 34.6%, and 38.9%, respectively. Compared with patients 65 to 79 years old, more patients ≥80 years old were at high stroke risk (CHADS(2) ≥2, 84.7% vs 57.8%) and high bleeding risk (ATRIA 5-10, 55.8% vs 23.3%). Warfarin use in both age groups increased with higher CHADS(2) scores and decreased with higher ATRIA scores. Of patients ≥80 years old with CHADS(2) ≥2, 150 (38.2%) received warfarin. Antithrombotic strategy was not associated with improved 1-year adjusted outcomes. CONCLUSIONS: Among older patients with AF and CAD, overall warfarin use was low. Patients ≥80 years old at highest stroke risk received warfarin in similar proportions to the overall cohort. Further investigation into optimizing antithrombotic strategies in this population is warranted.

ABSTRACT

BACKGROUND: Factor Xa and factor IIa (thrombin) play roles in thrombotic complications after percutaneous coronary intervention. M118 is a novel low-molecular-weight heparin that has been rationally designed to capture the desired attributes of unfractionated heparin (UFH) and low-molecular-weight heparin: Potent activity against factor Xa and IIa, predictable pharmacokinetics after both intravenous and subcutaneous administration, ability to be monitored by use of point-of-care coagulation assays, and reversibility with protamine sulfate. We performed a phase 2 randomized trial to evaluate the safety and feasibility of M118 in the setting of elective percutaneous coronary intervention. METHODS AND RESULTS: Overall, 503 patients undergoing elective percutaneous coronary intervention at 43 centers in the United States and Canada were randomized in an open-label fashion to 1 of 4 arms: UFH 70 U/kg, M118 50 IU/kg IV, M118 75 IU/kg IV, or M118 100 IU/kg IV. The primary outcome was the composite of death, myocardial infarction, repeat revascularization, stroke, thrombocytopenia, catheter thrombus, bailout use of glycoprotein IIb/IIIa inhibitor, or any bleeding through 30 days. The primary end point occurred in 31.1% of patients randomized to UFH and in 22.7%, 28.3%, and 30.1% of patients randomized to M118 50, 75, and 100 IU/kg, respectively. The primary analysis comparing the rates of the primary end points between the pooled M118 groups versus UFH demonstrated that M118 was noninferior to UFH at preventing percutaneous coronary intervention-related complications (28.4% pooled M118 arms versus 31.1% UFH). The adverse event profiles of M118 and UFH were comparable. CONCLUSIONS: This phase 2 randomized trial demonstrates that M118 is well tolerated and feasible to use as an anticoagulant in patients undergoing elective percutaneous coronary intervention and forms the basis for further investigation of this agent in ischemic heart disease.

ABSTRACT

CONTEXT: Several small studies have suggested that cardiac enzyme elevation in the 24 hours following coronary artery bypass graft (CABG) surgery is associated with worse prognosis, but a definitive study is not available. Also, the long-term prognostic impact of small increases of perioperative enzyme has not been reported. OBJECTIVE: To quantify the relationship between peak post-CABG elevation of biomarkers of myocardial damage and early, intermediate-, and long-term mortality, including determining whether there is a threshold below which elevations lack prognostic significance. DATA SOURCES: Studies (randomized clinical trials or registries) of patients undergoing CABG surgery in which postprocedural biomarker and mortality data were collected and included. A search of the PubMed database was performed in July 2008 using the search terms coronary artery bypass, troponin, CK-MB, and mortality. STUDY SELECTION: Studies evaluating mortality and creatine kinase (CK-MB), troponin, or both were included. One study investigator declined to participate and 3 had insufficient data. DATA EXTRACTION: Two independent reviewers determined study eligibility. The principal investigator from each eligible study was contacted to request his/her participation. Once institutional review board approval for the use of these data for this purpose was obtained, we requested patient-level data from each source. Data were examined to ensure that cardiac markers had been measured within 24 hours after CABG surgery, key baseline covariates, and mortality were available. RESULTS: A total of 18,908 patients from 7 studies were included. Follow-up varied from 3 months to 5 years. Mortality was found to be a monotonically increasing function of the CK-MB ratio. The 30-day mortality rates by categories of CK-MB ratio were 0.63% (95% confidence interval [CI], 0.36%-1.02%) for 0 to <1, 0.86% (95% CI, 0.49%-1.40%) for 1 to <2, 0.95% (95% CI, 0.72%-1.22%) for 2 to <5, 2.09% (95% CI, 1.69%-2.57%) for 5 to <10, 2.78% (95% CI, 2.12%-3.58%) for 10 to <20, and 7.06% (95% CI, 5.46%-8.96%) for 20 to ≥40. Of the variables considered, the CK-MB ratio was the strongest independent predictor of death to 30 days and remained significant even after adjusting for a wide range of baseline risk factors (χ(2) = 143, P < .001; hazard ratio [HR] for each 5 point-increment above the upper limits of normal [ULN] = 1.12; 95% CI, 1.10-1.14). This result was strongest at 30 days, but the adjusted association persisted from 30 days to 1 year (χ(2) = 24; P < .001; HR for each 5-point increment above ULN = 1.17; 95% CI, 1.10-1.24) and a trend was present from 1 year to 5 years (χ(2) = 2.8; P = .10; HR for each 5-point increment above ULN = 1.05; 95% CI, 0.99-1.11). Similar analyses using troponin as the marker of necrosis led to the same conclusions (χ(2) = 142 for 0-30 days and χ(2) = 40 for 30 days to 6 months, both P < .001; HR for each 50 points above the ULN = 1.28; 95% CI, 1.23-1.33 and 1.15; 95% CI, 1.10-1.21, respectively). CONCLUSIONS: Among patients who had undergone CABG surgery, elevation of CK-MB or troponin levels within the first 24 hours was independently associated with increased intermediate- and long-term risk of mortality.

ABSTRACT

Objectives: To describe the study design and clinical characteristics of patients in the Sertraline Pediatric RegIstry for The Evaluation of Safety (SPRITES). Methods: SPRITES is an open-label postmarketing study of development and safety outcomes in patients aged 6 to 16 years treated with sertraline (with or without psychotherapy) compared with psychotherapy alone for up to 3 years in the United States. Baseline data included demographics and psychiatric history. Primary outcomes included measures of cognitive and emotional development (Trails B, Behavior Rating Inventory of Executive Function [BRIEF]), physical development (height and weight), and pubertal status (Tanner Stage). Data were also collected on present/lifetime risk of suicide-related events using the Columbia-Suicide Severity Rating Scale. Results: SPRITES enrolled 941 patients between the ages of 6 and 16 years. Patients' baseline mean age was 11.9 years (2.9), 57.2% were female, and 84.8% were white. Most patients (78.4%) had an anxiety disorder, and 15.6% were diagnosed with obsessive-compulsive disorder. The mean age at onset of first mental illness was 7.9 years. A higher percentage of sertraline-treated patients compared with patients who received no pharmacological treatment received prior psychotherapy (59.0% vs. 34.4%, p < 0.001), psychotropic medications for a psychiatric disorder (14.1% vs. 3.3%, p < 0.001), and other non-sertraline selective serotonin reuptake inhibitors (8.6% vs. 1.2%, p < 0.001). Most patients were moderately ill on the Clinical Global Impressions-Severity scale, and a higher (p < 0.001) percentage of sertraline-treated patients had a moderate-to-severe mental illness score compared with the no pharmacological treatment group (73.0% vs. 57.8%, respectively). Although patients at high and imminent risk of a suicidal event were excluded at study entry, the sertraline-treated patients reported higher levels of lifetime suicidal behavior compared with patients treated with no pharmacological treatment (5.8% vs. 2.5%, p = 0.039). Conclusions: Baseline data from this nonrandomized observational study suggest that patients prescribed sertraline are reflective of a more mentally ill study population compared with patients receiving psychotherapy.

ABSTRACT

BACKGROUND: There are little data regarding outcomes in patients with angina and severe coronary artery disease (CAD) treated with medical management. Using the Duke Databank of Cardiovascular Disease, we describe the prevalence and long-term outcomes of patients with angina and multivessel CAD treated medically after catheterization. METHODS: Patients undergoing catheterization for angina (chest pain without recent revascularization or myocardial infarction) with severe CAD (>or=75% stenosis in >or=2 epicardial vessels) were identified (n = 8,555). One and five year outcomes in the 32% (n = 2,776) of patients who did not receive revascularization in the 30 days after catheterization were described. Predictors of 1-year death, cardiac rehospitalization, and late revascularization in this population were identified. RESULTS: The population had a median age of 66, were mostly male, had significant comorbidities, and most had prior revascularization. Outcomes were poor at 1 and 5 years: death (11% and 37%), cardiac rehospitalization (29% and 61%), and late revascularization (10% and 27%). The cumulative rate of death, myocardial infarction, late revascularization, or cardiac rehospitalization occurred in 38% at 1 year and 76% at 5 years. Prior coronary artery bypass grafting was the only variable independently associated with protection from death, cardiac rehospitalization, and late revascularization. CONCLUSIONS: Medical management after catheterization is a common in patients with severe CAD and angina. Of patients treated with medical management, one third will have a recurrent cardiac event within the first year highlighting the poor outcomes and high utilization of resources by this patient population.

ABSTRACT

BACKGROUND: Currently recommended anticoagulant agents used in the setting of percutaneous coronary intervention (PCI) inhibit, with varying degrees of intensity, 2 critical targets (factor Xa and/or IIa) of the coagulation cascade, yet they carry significant limitations. M118-a novel, rationally engineered heparin-provides consistent anti-Xa and anti-IIa activity with a constant anti-Xa:anti-IIa ratio over time. M118 also combines the desired anticoagulant effects of unfractionated heparin with the beneficial attributes of low-molecular-weight heparin, and may represent the next generation of heparin therapy in patients diagnosed with acute coronary syndrome. STUDY DESIGN: The EMINENCE trial is a prospective, randomized, open-label, multicenter phase 2 study that will evaluate the safety and feasibility of M118 as an anticoagulant versus unfractionated heparin in subjects with stable coronary artery disease undergoing PCI. The primary end point of the study will be the combined incidence of clinical events defined as the composite of 30-day death, myocardial infarction, repeat revascularization, catheter thrombus, stroke, thrombocytopenia, bailout use of glycoprotein IIb/IIIa inhibitors, and major or minor bleeding. CONCLUSION: The EMINENCE trial will assess the safety and feasibility of M118 as an anticoagulant in the setting of PCI and will provide important information to determine the appropriate therapeutic range of activated clotting time for M118 and the appropriate dose or doses to be explored in a phase 3 clinical trial.
